Title: Preparation of unsaturated carboxylic acid ester
Inventor: AOSHIMA ATSUSHI
IPC: B01J27/00
Filed: 1980-04-22
Abstract: PURPOSE: To prepare the titled compound in high selectivity even at a low temperature, by the liquid-phase oxidiation of propylene or isobutylene in the presence of an alcohol and O 2 , using an strong acid and a catalyst composed of Pd and Pb, Bi, etc. as components of the reaction system.  
     CONSTITUTION: In the liquid-phase oxidation of propylene or isobutylene in the presence of a straight-chain lower alcohol and O 2 , (1) a catalyst composed of Pd and at least one component selected from Pb, Bi, thallium, Te and Hg and (2) a strong acid (e.g. sulfuric acid, hydrochloric acid, etc.) are incorporated in the reaction system. The catalyst (1) is pref. the intermetallic compound between Pb and/or Bi and Pd. Addition of an alkali metal or alkaline earth metal compound during the preparation of the catalyst improves especially the selectivity and the reaction activity of the catalyst. The process gives only a small amount of side products such as CO 2  and has high conversion of the raw material.

Abstract: PURPOSE:To prevent welding to a semiconductor element of a flexible substrate, and to inject a sealing resin easily by projecting the lower surface of a semiconductor element loading section in the flexible substrate with a small sealing hole toward the rear from the surface oppositely faced to the semiconductor element. CONSTITUTION:A sealing hole 2a is bored previously to the lower surface of a loading section for a semiconductor element 1', and the lower surface of the loading section for the semiconductor element 1 is sucked, avoiding the sealing hole 2a so as to projected toward the rear from the surface oppositely faced to the semiconductor element 1 of a flexible substrate 2 by a suction jig 4. The semiconductor element 1 positions solder bumps 1a and a copper foil pattern for the flexible substrate 2, and is heated from the upper surface of the semiconductor element 1. Since the flexible substrate 2 is sucked so as to be protruded from the rear, it is not welded to the semiconductor element 1. The semiconductor device is filled with a liquefied epoxy group sealing resin from the sealing hole 2a. The sealing resin is injected easily into a clearance d' between the lower surface of the semiconductor element 1 and the surface of the flexible substrate 2, and the sealing hole 2a may also be scaled down, thus also keeping a bonded surface largely.
